Use the "0 dBSPL - Hearing Threshold, 1 Pascal" pulldown to select different environments using the following site:

Site shows 30 dBSPL as whisper and 60 dbSPL as normal conversations. Many others.

Jordan is right give him the points. The typical range of human hearing for a child is approximately 20 Hz to 20 KHz, but very few of us over 18 years of age can hear 20 kHz, I do a lot of noise induced hearing loss training and run experiments with guys in the class. Most are lucky to still be playing above about 14 kHz and several below that. But they are older and have been exposed to a working life in a noisy environment. So yeah, it is widely accepted that the range of human hearing is 20 Hz to 20 kHz.

a normal speaking voice outdoors might be 20 db, a loud shout might be 40 db. lot of variables. If you mean frequency range, an adult usually speaks/sings around middle C which, last I checked, is a suprisingly low 260 Hz. This is a tone that any human voice, man or woman, should be able to achieve.
